Is Mountain Lion on retina MacBook Pro really this buggy?

I've had my retina MacBook Pro 2,6 GHz 16 GB version for almost a week now, and its fantastic in so many ways. The retina display is the most stunning display I've ever seen, and I really enjoy using my MacBook because of it.

However, I've noticed that a broad spectre of Mountain Lion is buggy as nothing I've ever used from Apple. For instance, Safari is at times nearly unusable.

- I've seen this been discussed here before, but I still want to bring it up again. Scrolling is not what I'm used to. Depending on which site I visit, it ranges from almost perfect (i.e. MacRumors, reddit and even some image heavy blogs and news sites) to utter garbage. Facebook being the absolute worst. When scrolling down my news feed, it often feels like a slide show with around 2 fps. Laggy as nothing else.

- Typing also is a pain. Text goes invincible, then to appear again, and then disappear again, seemingly at random. Sometimes one line of text is overlapping the previous line, and it's basically a complete mess. This could be from the autocorrect function, as I've noticed sites like facebook are far worse than when I'm writing now, for instance (on facebook I write in norwegian which has no dictionary yet, while this is obviously in english).

Scrolling is a problem not only in Safari, but also in other parts of Mountain Lion.
- In example, scrolling through my iTunes library is not as fluid and smooth as it was on my iMac running Lion. While smoother than scrolling facebook in Safari, it still is sub-par fps and feels laggy.
- However, scrolling through exremely high resolution photos in Aperture is smooth as butter, even still when I have tons of thumbnails on screen at the same time.
- This suggest that this is a software problem, not a hardware problem like I've seen suggested on this forum before.
- Even the OS itself sometimes is laggy, with occasional visible hiccups in the animations when I'm switching apps with Mission Control. This, however, is very rare (and it doesn't seem to correspond with the number of apps I'm running at the same time)
- Basically, there are good and bad apps when it comes to smooth graphics. Good ones being most of the standard apps, while App Store, Safari, Calendar and iTunes seems to be the worst.

Anyone else experincing the same with their retina MacBook Pro? Suggestions? Are Apple working on this?

Have you tried forcing the discrete graphics to see if it's lag coming from the Intel chip?

The Safari rendering problems are really annoying. Windows on the rMBP is less buggy than OS X, which is really ironic.

So can we confirm that this problem is not unique to my Mac, and is in fact something that appears on every MacBook Pro retina?

I have 5 days left of my open return, so it would be great to know if I should return my MacBook or wait for Apple to release a software update. I don't have an Apple Store in my country, so there are no Apple staff that can help me, other than over phone (which sucks).

Also just got my rMBP with the same specs (2.6GHz with 16GB RAM) this past week and have not had any issues at all. No scroll lag at all on Safari (or other browsers), no text disappearing or image overlapping on Safari, no app "pop up" lag, no WiFi problem, no problems at all. This computer wasn't cheap, but I can't be any happier absolutely love it.

Also, I have the auto-graphics switching checked on. Are you guys all up to date with software (running 10.8.1, heard it fixed a lot of stuff)?

Interesting. Could you try to load and scroll at various speeds on these two sites, and post results?

omg really? i wish mine didn't have those issues

can you try to expand a windows (try Chrome, horizontal and vertical) and see if it feels very laggy??

the wifi problem really bugs me... i was skyping with my gf and it DCed me twice within 1 hour

and when i exit from full screen it not smooth at all.. feels like I'm using an ancient pc with no graphic card (if it makes sense)

So I went to an Apple Premium Reseller today (not Apple Store, they don't have one in Norway, and thus no geniuses) and compared my retina Mac to the demo models.

The demo model, which was a 2,3 GHz 8 GB RAM one, performed significantly better than my 2,6 GHz 16 GB RAM retina Mac. The scrolling on www.aftenposten.no is horrible on my computer, while constant at about 30 fps (or maybe a little lower) on the demo model.

However, the demo version was running Lion, and not 10.8.1 ML as mine. I fail to see how this should make my computer slower still, as most of the other users that report the same problem seem to have had issues since Lion.

The guy in the store also said a friend of him got the retina Mac recently without the UI lag.

Could this indicate a GPU problem?

I tried the web site with my MBPr running on battery. If use the integrated HD4000 GPU, scrolling is very laggy. Once switched to the discrete GPU, it was much better. But still far from smooth as butter.

Either the hardware is not sufficient for the high resolution, or ML is still not fully optimized to take advantage of all hardware capabilities. I'm running 10.8.2 latest beta.
